Hello Rob (I m really sorry for the delay on the answer)
If you want to replace the heater core yoursel let me know and I can explain you the way you can do it (on this especific car its really Easy.)
my advice: before you get ready to replace the heater core take your car to a radiator shop and ask them to "flush" the heater core (by unplugin the inlet and outlet hoses from the core) I m telling you "before are you ready" because the heater core could be "weak" and could after the flush have a leak.
That its a risk (flip a coin) could get fix could get a leak.
Let me know if you want a do it and I guide you no problem!
Good Luck !
